Application filed March 26, 1921. Serial No. 455,776.

To all whom z't may concern.'

Be it known that I, JOHN LINDGREN, a citizen of the United Statesyresiding at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Methods and Means for Wrapping Hair Nets, of which the following is a full, clear, and exact description.

This invention relates to an improved method of and means for wrapping various articles, such as hair nets for shipment and sale.

As is well-known, hair-nets at present are manufactured in large quantities of different shades and mesh and cut to the desired size and shape and placed in paper receptacles such as envelopes, which are packed in large quantities for shipment. Often, a number of the nets are placed in one envelope, or they may be placed in individualenvelopes, for sale. However, considerable time is consumed at the factory in placing the nets in the envelopes, it being necessary to exercise extreme care in handling the nets and where a number of nets are inserted together they become entangled in the course of handling, and sometimes are torn or otherwise rendered useless when it is attempted to separate them.

It is an object of my invention to provide an improved method of and means for wrapping and the folding of hair-nets and similar articles quickly and securely in such a way that tangling ofthe individual nets is impossible and so that they are well protected and kept sanitary, in course of shipment and handling. I also contemplate the saving of time and labor in the wrapping of the goods at the factory, so that the cost of production may be reduced materially.

A more concrete understanding of my invcntion may be obtained from the following detailed description and the claims, taken in connection with the accompanying drawings, in which Figure 1 is a plan view of an article of 'manutan-ture, such as a hair-net, placed upon the envelope, in the first step.

Figure 2 is a perspective view of the manual rolling member.

Figure I; is a side elevation showing the roller applied to the net and envelope for rolling the same, the second step.

Figure 4 is an cud view of the envelope llattened, the third step.

Figure is a perspective view of the envelope containing the net, folded, the last stelp.

ligure 6 is a top plan view'of a mechanical means for carrying out the method involved here.

Figure 7 is a longitudinal vertical section of the same, taken on line 7, 7, of Figure 6. Figure 8 is a transverse vertical section taken on line 8, 8, of Figure 6, looking in the direction of the arrows.

Referring to the drawings, and more particularly to Figures 1 to 5, inclusive, I provide manually means and employ a method for wrapping the hair-nets, the envelope 10, taking, preferably, the form of a rectangle of suflicient area to permit the hairnet 11 of any desired shape to be placed fiat tl1ereon, with spaces 12, l2, between the edges of the net and envelope allowing for retraction of the sheet or envelope length when rolled, as wlllappear presently. After placing the net fiat on the sheet, the roller 13 is placed at, say,the end 14 of the sheet, and the latter rolled upon said roller, as at 15, (Figure 3), the sheet and net being completely rolled upon said roller with the convolutions of the net within those of the envelope; thus completely enclosing the net. As a general rule, there will be one'net in each envelope, but., i'f desired, a plurality of nets or alternate envelopes'and nets might be provided. After rolling the sheet and its contents to a cylindrical shape, the roller is removed and the cylinder formed thereby is flattened to an elliptical shape, are then folded at the medial portion, as indicated at 16, and the complemental ends 17, 17, may then be coupled by adhesive tape, or in `any other manner desired. The removal of the net may be quickly accomplished without danger of tearing or otherwise mutilating the same; the net being maintained smooth and ready for use( The method explained hereinbefore may be carried out in the same fashion by the mechanical means illustrated in Figures G to 9, inclusive, wherein 18 indicates a table having legs 19, 19, support-ing a top 20. A platen 21 isplaced on the top 20, andis provided with longitudinal spaced divergent trackways or grooves 22 and 23, spreading from the front end 24 to the rear end 25 of the table. Stops 26 and 27 are placed on alongside their respective trackways.

llt)

Means for rolling the envelope and net are provided and consists of two carriage sections 2n and 29 in the form of tapered blocks having airs of wheels 3() and 31 journaled on tie outer inclined faces 32 and 33, and operating in the trackways 22 in the table and platen and arranged near.

the rear end of said table and centrally of said trackways.

surface ot' the table t-op 20, is pivotally con'- nected at its rear end by a link 45 to the The front end of' lower end of the blade. the lever extends beyond the table and is provided with a pedal 46.

The blade 40 is adapted to be raised through the slot 41 by downward pressure on the pedal 46, this blade passing u midway. between two spa-ced jaws 47, 4 carried by the horizontal spaced arms 48, 48,.

formed on the standard 49, which latter is rigidly secured to the platen 21, at its'rear end; The lower extremities of the jaws 47, 47, are flared andgcooperate with the blade for a purpose which will presently appear.

In carrying out the method described hereinbet'ore with this apparatus the two carriages 28 and 29 are brought to the front end of the table and their respective rollers are arranged in substantially axial alinement, the trackways bringing the opposing ends of the rollers into abutting engagement, forming practically a: continuons roller. The stops 26 and 2T engaged by the the carriage insure the rollers heilig in .axial alinement. An envelopesuch as the sheet 10 is now placed on the platen with its front end beneath the rollers 34 and 35; a hairnet is .placed on this sheet, the rollers` (Shown in Figure 3), and their rollers move toward the rear of the table, the sheet and hair-netbeing rolled thereon. 'Ihe cylinder thusformed is moved with the rollers until the medial portion of the cylinder abnts the standard 49 and is over the slot 4l. At this time, by virtue of the divergent arrange- .ment of the trackways the carriages and their rollers will be well separated. and the rollers ready to discharge the cylinder when the blade is moved upwardly, A quick dcpression of the pedal 46 causes'the blade to force the medial portion-oi the cylinder against the jaws 47 and continuing this mo- A lever 42, fulcrumed atl 43 in a frame 44 supported on the 'under tion folds and lattens the cylinder between these jaws.` The folded finished product is.

then grasped and removed from the to open ends ot the jaws and sealed if desire The carriages arethen returned for another operation. The table is of such length so as'to permit the operator to reach from one end to the other, so that, one man can rapidlyand eliciently wrap and fold lmany of the products in a short time.
